To all whom it may concern Be it known that I, JOHN C. WUELLNEn,

- a citizen of the United States, and a resident ofthe cit of Alton in the county of Maditate of Illinois, have invented certain new and useful Improvements in Knockdown-Building Structures; and I do hereby declare that the following is a full, clear, and exact-description of the same,

E reference "being had to the accompanying drawings, and to the numerals of reference marked thereon, Which'form a part of this sp'etification.

This invention relates to an improved knock down construction for concrete distributing towers, pile drivers, derricks, and other structures, whereinra id erection of the structure is desirable eit er for temporary or permanent use, and, in any event,

.' capable of being rapidly taken down or dismantlediforreconstruction at another point if-sodesired.

It is an object therefore of this invention to provide a knock downconstruction for towers and other similar structures which me be 'rapidl assembled, requirin only the attachmentyof bolts to hold the struc- 'tura-l members assembled, and in rigid braced relation.

It is also an object .of this invention to wherein the various members of the structure are held 'asembled by specially designed fittings reiiuiring only the attachace to hold the members tion either for temporary or permanent use. It is-furthermore an important-object of this invention to provide-an; easily assembled 40 knockdown form of tower or other. strucvture' for any purpose whatsoever, which ma be erected toany heightdesired,-and with a l the members interchangeable, thus provide ,ing' a standardized construction, easily erected without requiring the services of parts arexinterchangeable, are he'ldas Ipeoifloation 0!

sembled by the use of specially designed fittin which are likewise interchangeable so the a standardized form of structure-is provided, capable of erection to any liei ht desired in a short space of time, either or temporary or'permanent use. The invention (in apreferred form) is illustrated in the drawings and hereinafter more'fully described.

On the drawin Figure 1 is aragmentary side elevation of a tower'str. :ture, constructed according to the principles of my invention.

Fig. 2 is a similar view of a modified -form of structure.

Fig. 3 is an enlarged fragmentary side'elevation showing a typical panel in the-form of structure shown in Fig.1.

Fig. 4 is a detail section taken on. line HofFiga Fig. 5 is a detail section taken on (line 5-5 of Fig. 4.

Fig. 6 is a detail section taken on'lihe 6'-6 of Fig. 5 I i Fi 7 is a detail section taken ori-line 77 of Fig. 4, with parts shown in elevation.

here, the upright onesof which are denoted by. the reference, numeral 1, and the' hor-i zontal members of which are denoted byfthe reference] numeral 2, said structure? as clearly shown in Fi 4 having all identical and without interior conne'i lm The various transverse and upright mom] ers of the structure are held assembled at the ends or at. the junction- 0f the ends thereof by corner brackets, all of which are identi cal in construction. Each of said corner bracketsconsists of an integral angled plate 3, the walls of which are bent at right angles to one another, as clearly shown in Figs. 4

and 7, and said plates are fitted around the upright members 1, at the 'unction thereof, and are held rigidly secure thereto by bolts 4 and 5, respectively, which are at right angles to one another and are bolted through apertures provided therefor in the ends of.

the respective abutting upright members 1. Said bolts 4 and 5, serve to hold attached upon the inncrsurfaces of the res eetive abutting upright members 1, flat p ates 6, against which the ends of the horizontal members 2, abut, as clearly shown in Figs. 4 and 7. The margins of theright angled bracket plates 3', extend be ond the uprights 1, on each side thereo as shown in Figs. 6 and 7, and are provided with apertunes to receive U-bolts 7, engaged therein which fit around the respective transverse horizontal members 2, to support the same inposition.

ttached through apertures at the corners of the projecting ends .of the corner plates 3, are bolts'8, which serve tohold connected thereto, tie rods 9, arranged in diagonal relation in each side panel of the erected'structure. Each tie rod 9, is provided with a turn-buckle 10, whereby the same may be tightened, said tie rods thus acting as tension members, and the transverse member 2, acting as compression members in the erected structure. Attached by means of bolts 12, on the'inner surface of each of the transverse horizontal member 2, are

blocks 11, and extending vertically in parallel relation on the interior of the erected,

structure, are upright members 13, which .are attached to said blocks 11,, affording guides for an elevator by which material is carried to'the upper end of the structure.

As shown diagrammatically in Fig. 1, a

discharge hopper 14, is mounted at'the upper end of the structure when the structure is used as a distributing tower, into which an elevator may discharge its contents such as concrete mixture, and below said hopper 14, is a mouth 15, of a gravity conveyer lead- :ing downwardly and by which the concrete is distributed. l

. In the modified form of structure illus- 'itrated in Figs. 2, 8 and 9, the upright members are denoted by the reference numeral 16', and as clearly shown in Fig. 2, are con- I vergently arranged and are held attached at the junction'of their ends by corner bracket plates 17, whiclrare bolted to the ends of the upright niembers 16, by means of bolts 18, extending at right angles therethrou h, vhas clearly shown in Fig. 9. Also, as in 516 construction previously described, tie rods 19, are connected in diagonal relation between each of the side corners of the structure in said vertical panel. in the'previous construction described,

members are provided, denoted by the reference numeral 20, those at different heights in the structure being of different lengths due to the convergence of the upright members. Plates 21, areheld attached upon the inner surfaces of the upright members at the oint of abutment of the ends of the memers 20 thereagainst, and struck outwardly from each plate is an extension 22, which affords a support for the end of a transverse horizontal member 20. Said horizontal members'20, are each further supported by U-bolts 23, secured to the corner bracket plates 17.

, In the form of structure illustrated in Fig. 2, a tank 24, is. shown supported at the upper end thereof, merely to show one of the possibilities of this type of structure when erected for permanent use. Y

In the form of structure illustrated in -Fig. 1, the elements are generally only assembled for tern orary purpose, such as in a concrete distri uting tower, and are usually erected to considerable height, and the structure is then held secured by guy wires or cables, (not shown) which extend from the upper end of the tower to points at a distance, on the ground.

I am aware that the details of construction may be varied through a wide range without departing from the principles of this invention, and'I therefore do not pur- -pose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. A knock-down structure, comprising upright members arranged abuttin and in alined relation, transverse mem ers arranged to abut said upright members at the junction thereof, corner attaching plates of angle shape bolted-to the abutting ends of the upright members, and U-bolts engaged through said plates at theends thereof and encircling ,said transverse. members to support the same in position.

2. A knock-down structure, comprising a plurality of interchangeable upright and transverse members arranged with their ends abutting one. another, angled corner shape bolted to'the abuttingof t e 'upright mem ers, U-bolts thro gh" 'Ih testl mony whereof Ihsve M said plates at the ends thereof and encircling scribed niy name in thepresence of two sub- 7 said transverse members to support the same scribing witnewes." 4' in 'sition, and tie rods connected in diago- JOHN C.
